If you’re lucky, the developer has included uninstall instructions in the install script and then
make uninstall
will just work, but please note that’s a big if.
If it doesn’t (and I’m unfamiliar with the software you installed so can’t tell you) , you, as the system maintainer should have used:
checkinstall
OR- created a
PKGBUILDand then you can just use standard Manjaro tools to uninstall
If you didn’t use either of the above, please read this:
Especially the section “How to install Software”, because now you’re in for a re-install. ¹
None 1 Unless you’re a developer yourself and then you can read the install script and painstakingly and manually undo all the changes it made…
